Abstract
The utility model relates to an electric vehicle capable of running along tracks for children, which comprises a vehicle main body, one pair of front wheels which are arranged on the bottom front parts of the vehicle main body in a rotating mode, one pair of rear wheels which are arranged on the bottom rear parts of the vehicle main body in a rotating mode and at least one pair of middle wheels which are arranged between the front wheels and the rear wheels, wherein tracks are arranged under the front wheels, the rear wheels and the middle wheels, holes for middle wheel shafts are arranged on the vehicle main body, middle wheel shafts are penetrated through the holes for the middle wheel shafts, the middle wheels are respectively arranged on the two end parts of the middle wheel shafts and the middle wheel shafts are provided with the vehicle main body in a slide mode along the axial direction. When the electric vehicle capable of running along tracks for children runs on the circular arc-shaped tracks, one pair of middle wheels generates displacement relative to the vehicle main body along the axial direction of the middle wheel shafts. Thereby, one middle wheel can not interfere with the circular arc-shaped tracks, so the electric vehicle capable of running along tracks for children can run smoothly on the circular arc-shaped tracks.
Description
Technical field
The utility model relates to a kind of children's electric motor vehicle along rail running.
Background technology
Of the prior art, children's electric motor vehicle along rail running, comprise the car body, be arranged on a pair of front-wheel of the front portion, the end of described car body rotationally, be arranged on the pair of rear wheels at the rear portion, the end of described car body rotationally, be arranged at least one pair of breast wheel between described front-wheel and the described trailing wheel, described front-wheel, trailing wheel, the below of breast wheel is provided with track, common described front-wheel, trailing wheel, breast wheel all be axial restraint be arranged on the described car body, when on arc orbit, moving, as shown in Figure 4, a breast wheel de-orbits, another breast wheel then with the track interference, therefore this children's electric motor vehicle can only can not move on arc orbit in operation on the straight rail.
Summary of the invention
The utility model purpose provides a kind of children's electric motor vehicle along rail running, and it also can move on arc orbit.
For achieving the above object, the technical solution adopted in the utility model is: a kind of children's electric motor vehicle along rail running, comprise the car body, be arranged on a pair of front-wheel of the front portion, the end of described car body rotationally, be arranged on the pair of rear wheels at the rear portion, the end of described car body rotationally, be arranged at least one pair of breast wheel between described front-wheel and the described trailing wheel, described front-wheel, trailing wheel, the below of breast wheel is provided with track, have the breast wheel axis hole on the described car body, wheel shaft in the middle of having passed in the described breast wheel axis hole, the both ends of wheel shaft are provided with breast wheel respectively in the middle of described, and described middle wheel shaft is provided with the car body axially slidably mutually along it.
Because technique scheme utilization, the utility model compared with prior art has following advantage: when children's electric motor car moves on arc-shaped rail, described a pair of breast wheel produces displacement along the axially described relatively car body of described middle wheel shaft, thereby one of them breast wheel not can with the arc orbit interference, thereby children's electric motor vehicle also can be on arc orbit operation reposefully.

The specific embodiment
As shown in Figure 1, a kind of children's electric motor vehicle along rail running, comprise car body 2, rotationally be arranged on a pair of front-wheel 3 of the front portion, the end of described car body 2, rotationally be arranged on the rear portion, the end of described car body 2 pair of rear wheels 5, be arranged at least one pair of breast wheel 4 between described front-wheel 3 and the described trailing wheel 5, the below of described front-wheel 3, trailing wheel 5, breast wheel 4 is provided with track 1.
As shown in Figure 2, have breast wheel axis hole 7 on the described car body 2, wheel shaft 6 in the middle of having passed in the described breast wheel axis hole 7, the both ends of described middle wheel shaft 6 are provided with breast wheel 4 respectively, and described middle wheel shaft 6 is provided with car body 2 axially slidably mutually along it.Described breast wheel 4 is permanently connected with described middle wheel shaft 6, and described middle wheel shaft 6 is provided with rotationally with respect to described car body 2.Be provided with elastic component between described car body 2 and the described breast wheel 4.Described elastic component is a spring 8, and the two ends of described spring 8 are against respectively on described car body 2 and the described breast wheel 4, and described spring 8 is enclosed within on the described middle wheel shaft 6.The two ends of described spring 8 are packing ring, and a described packing ring is against on the described breast wheel 4, and another is against on the described car body 2.When children's electric motor car runs on the arc orbit, described a pair of breast wheel 4 produces displacements along the axially relative described car body 2 of described middle wheel shaft 6 simultaneously with described middle wheel shaft 6, when children's electric motor car when moving on the straight rail from arc orbit, spring 8 makes a pair of breast wheel 4 reset simultaneously with middle wheel shaft 6.
Shown in each accompanying drawing, has the chimb 10 that radially becomes big on described front-wheel 3, trailing wheel 5, the breast wheel 4, described chimb 10 is an arcwall face 9 with described track 1 contacted surface, as shown in Figure 3, thus a pair of front-wheel of children's electric motor vehicle 3 runs on the arc orbit 1 by arcwall face 9 respectively reposefully with pair of rear wheels 5.
